How to better encrypt a string? MD5, RSA, DES?Well, none of this is understood.Reference to the degree Niang, so the idea is:For encryption:· Remove a character from the string to be encrypted· The low-byte and Key1 of the characters are taken to make an XOR operation· Take the high byte of the character· Synthesize the data after the operation to a new characterFor decryption:· Remove a character from the string to decrypt· The low-byte and Key1 of t

Ben Bovinlai chat How to play asymmetric encryption bar, here is mainly introduced. NET algorithm, 3 kinds of asymmetric encryption algorithms: DSA,RSA,ECDSA. The two blog posts have found the lead for the hash family and the asymmetric encryption family, so let's find the right lead for asymmetric cryptography. First create an interface: "Iencryptanddecrypt", a

We will share this with you for your reference. The details are as follows: 1. Encrypted File 2. decrypt the file PS: if you are interested in encryption
homomorphic Encryption (homomorphic encryption) is a form of encryption that allows people to perform certain algebraic operations on ciphertext to get the result that is still encrypted, and the result of decrypting it is the same as the result of the same operation on the plaintext. In other words, this technology enables people to perform operations such as

Computers are used for office and study. It is a headache to protect our privacy and security. To protect important documents from being browsed by third parties, Special encryption/hiding tools are usually used to encrypt or hide them. In fact, we can directly encrypt text files in the Internet Explorer browser, and it is easy to use -- Encryption principle: Not encrypted by adding a password, but by chang
From: http://snowolf.iteye.com/blog/380034 Next, we will introduce symmetric encryption algorithms. The most common is des data encryption algorithms.Des Des-Data Encryption Standard, which is the data encryption algorithm. It was published by IBM in 1975. The DES algorithm has three entry parameters: Key, data, and mo
Full version of MD5 Encryption Algorithm in Java, javamd5 Encryption Algorithm Some data is inevitably encrypted during Java software development. Therefore, Java provides its own MessageDigest to implement text encryption algorithms, the following is an example of the MD5 encryption tool code for text
I have not found any good DES encryption code for a long time. It is no wonder that a blogger said that he had not found himself for a long time. Http://www.iteye.com/topic/422575 But it seems that he said that the encrypted plaintext will go wrong, so I did not dare to try it out. In addition, I downloaded one from Tiandi, and found that the function was still possible. It seems that I switched the js version. However, the
